Humbly, We swim in a sea of energy – the aether.  In fact, particles are standing waves of energy in the sea.

And free energy tech draws on that energy in the aether.

The work of the late Dr. Paul A. LaViolette, called subquantum kinetics (SQK), where He took an "as above, so below" approach, applying chemical kinetics to the subquantum, shows that there is an aether, and that We can draw on the energy there freely.

When He first saw that, He thought He had erred, and combed His work over and over looking for where He had done so.  Then He encountered the work of T.Townsend Brown – who My father was working with on electrogravitics – and saw that Brown was demonstrating precisely what SQK predicted.

Yes, energy is free.  Or would be if the moneyed psychopaths did not avidly hide and suppress the tech.

And BTW...  SQK is a counter theory to the einsteinian bunk that was foisted onto Us because it did not predict the energy in the aether, with all its ad hoc additions ("dark matter," "dark energy," etc.), its "renormalaizations" where the math goes to infinity and reality does not, "mysteries," and "bending of spacetime" (another ad hoc element.

SQK needs no ad hoc things, no renormalization, has no "mysteries, and is euclidean.
